By moving the first magnesium anode (installed as
standard in the vertical position) to fitting (11), an
expansion vessel/safety system can be connected directly

storage cylinders are delivered without
a boiler heating pump. A suitably rated pump must be
provided and installed separately.
9
The domestic hot water system MUST INCLUDE an expansion
vessel, safety valve, automatic vent valve and storage
cylinder drain cock.
9
The safety valve must be connected to a suitable
collection and drain system. The manufacturer declines all
responsibility for damage caused by water escaping from
the safety valve.
9
The choice of system components and the method of their
installation are left up to the heating engineer installing the
system. Installers must use their expertise to ensure proper
installation and functioning in conformity to all applicable
legislation.
9
Circuits filled with anti-freeze must be fitted with water
disconnectors.
